BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a device for setting a maintenance work position of an escalator, and more particularly to a method and a device for removing a part of the escalator to provide a work opening. The present invention relates to an escalator maintenance work position setting method and an escalator maintenance work position setting device for performing maintenance work while stopping required equipment inside an escalator while operating the escalator.

[0002]

2. Description of the Related Art Conventionally, in this kind of maintenance work,
Several steps of the escalator are removed to provide a work opening, and while the escalator is operating, this work opening is stopped at a work position suitable for the maintenance work of the target equipment, and the maintenance work is performed. Was.

[0003] However, in the past, the work opening had to be adjusted to a suitable position for each device to be subjected to maintenance work each time, and the work was performed by two persons. That is, since the target device is disposed inside the escalator, the position of the required device cannot be directly seen from the operation control position side of the escalator, and therefore, the working position is preferably set to a suitable working position. In order to stop the work opening, trial and error would be repeated for one-person work, and two people were inevitably performed.

A description will be given below with reference to FIG. FIG. 3 is a conceptual diagram of a configuration of a conventional escalator. In FIG.
Symbol A indicates the inside of the escalator, 1a, 1b, 1
Reference numerals c and 1d denote, for example, first to fourth four driving machines as required devices which require maintenance work and are disposed inside the escalator A. 2 is an escalator step; 3 is an operation control means for controlling the operation of the escalator; 4 is a work operation control means connected to the operation control means; and 5 is a worker. The symbol B in the figure is the step 2 of the escalator.
This is a work opening that has been opened to make the inside visible.

When a maintenance work is to be performed on the driving machine 1d provided in the escalator interior A, one worker 5 operates through the work operation control means 4 connected to the operation control means 3. The operator tries to operate the escalator so that the working opening B is in a suitable working position with respect to the required required equipment, that is, the driving machine 1d. The driver 1d as a required device cannot be visually recognized. Therefore, depending on the feeling, the worker 5 first stops the escalator once so that the work opening B is located at the approximate position, and then goes out to the position of the work opening B of the escalator, After determining the current positional relationship between the driving machine 1d and the working opening B, return to the original position, drive the escalator again, and stop the escalator so that the working opening B is located at the predicted position. It was. Therefore, it becomes difficult and complicated for even a skilled worker to work alone, and for an unskilled worker, the positioning work, that is, the setting of the work position, must be repeated many times.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 A maintenance work position setting method and a maintenance work position setting device for an escalator will be described with reference to FIGS. 1 and 2 showing the first embodiment. FIG. 1 is a conceptual diagram showing the configuration of the escalator, and FIG. 2 is a control circuit diagram. In FIG. 1, the illustrated escalator is provided with a work opening B by removing a part of step 2 and stopping the work opening B at a suitable work position for required equipment inside the escalator while operating the escalator. This is a type in which maintenance work is performed.

As the required equipment, four driving machines 1a, 1b, 1c, and 1d, which are disposed inside the escalator and require maintenance and inspection work, will be described. Now, when the operator 5 drives the escalator provided with the working opening B, the working opening is moved to a predetermined working position (position shown in the drawing) predetermined as a suitable working position for the driving machine 1d. When B moves, an optical sensor 6d as an opening detecting means disposed with respect to the driving machine 1d detects the moving working opening B and sends a detection signal to that effect to control the escalator. Send it to the control means 3.

The operation control means 3 stops the escalator based on the detection signal from the optical sensor 6d as the opening detecting means. Thereby, the working opening B can be reliably moved to a suitable working position (the position shown) with respect to the driving machine 1d. In this embodiment, the optical sensor 6d as an opening detecting means for the driving device 1d as a required device to be subjected to maintenance work is replaced with the driving device 1d.
d, but it is not limited to this, but the point is that the working opening B is located at a position suitable for maintenance work on required equipment.
It is good if the opening detecting means is arranged at a position where the opening can be detected, and the detecting means is not limited to the optical sensor, and can detect that the working opening has moved to a predetermined position. Any detection means is good.

In FIG. 2, the operation control means 3 includes a plurality of driving machines 1a, 1b, 1c, 1
A switch 7 is provided as an opening detecting means for d, which can selectively switch detection signals sent from a plurality of optical sensors 6a, 6b, 6c, and 6d as appropriate. The illustrated switch 7 is used to select one of the target driving machines 1d,
Through 4, the working opening B can be moved to a suitable position with respect to the driving machine 1d.

That is, in the above example, when the driving machine 1d is intended, when the escalator is operated by setting the switch 7 as the switching means of the operation control means 3 to 1d, the working opening B is opened. When the optical sensor 6d moves to a position detected by the optical sensor
The A contact 30 of d turns on, the stop relay 24 is excited, and the operation relay 23 is activated by the B contact 26 of the stop relay 24.
Disappears, the power supply to the escalator is cut off, and the escalator stops. As a result, the work opening B is located at a work position suitable for the target driving machine 1d.

The driving device 1 as another required device
The optical sensors 6a, 6b, 6c as the opening detecting means of the working opening B with respect to a, 1b, 1c are the same as above. In FIG. 2, reference numeral 21 denotes an up operation relay, 22 denotes a down operation relay, and 25 denotes an operation relay.
a and 25b are A contacts of the operation relay, and 27, 28 and 29 are A contacts d of the optical sensors 6a, 6b and 6c, respectively.
